You're doing it wrong.

1. You don't set resolutions in the URL, you set them in the config
   file.
2. Your image size is 602,593: this seems unlikely to be the tilesize
you've picked in your TileCache config.
3. extent_type=loose also goes in the config, not in your URL.

No.

No, it doesn't. If you think it does, something is wrong. Paste your
config for the 'basemap' section to the list, if you want someone to
look at it. If you're using mod_python, and you changed your config,
restart Apache.
